This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/6

18、86/EEC. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Bel

EN 511:2006 (E) 4 1 Scope This

20、European Standard specifies the requirements and test methods for gloves which protect against convective and conductive cold down to 50 C. This cold can be linked to the climatic conditions or an industrial activity. The specific values of the different performance levels are decided by the special

21、 requirements for each class of risk or the special areas of application. Product tests may only give performance levels and not levels of protection. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

25、EN 388 in abrasion and tear resistance. This minimum requirement can be different according to the levels of protection against cold (see 4.5 and 4.6). 4.2 Flexibility behaviour When tested in accordance with 5.2 there shall not be any cracks. This test is not necessary for uncoated materials. 4.3 W

26、ater penetration The gloves shall be tested according to 5.3. A level of performance of 1 shall be indicated when no leakage is seen at the end of the testing period. If this requirement is not passed, then a performance level of 0 shall be indicated, and a warning stating that the EN 511:2006 (E) 5

27、 glove may lose its insulative properties when wet shall be added in the information supplied by the manufacturer (see Clause 7). 4.4 Extreme cold flexibility test When tested in accordance with 5.4 no crack shall appear at the fold. This test shall be performed on gloves designed to protect at temp

28、eratures below 30 C. 4.5 Convective cold When tested in accordance with 5.5, the thermal insulation properties of the glove shall comply with the values given in Table 1.

30、thermal resistance properties of the material shall comply with the values given in Table 2.

31、ecord at least level 2 in abrasion and tear resistance according to EN 388, otherwise the maximum contact cold performance that shall be reported is level 1. EN 511:2006 (E) 6 5 Test methods 5.1 Conditioning Except for the convective cold test, before testing, the samples shall be stored for a minim

32、um of 48 h in the following standard atmosphere: temperature (23 2) C; relative humidity (50 5) %. The test shall be preferably carried out in this atmosphere. If the test is carried out under different climatic conditions then it should be started within 3 min of the time the samples were removed f

33、rom the standard atmosphere. For protective gloves with a multi-layer construction the test shall be carried out on all layers simultaneously, even if these, when removed, are not connected to one another (see 5.5). 5.2 Flexibility behaviour The test shall be carried out in accordance with Method A

34、of EN ISO 7854:1997 at a test temperature of (-20 2) C or an alternative temperature as specified by the gloves manufacturer. The number of cycles shall be 10 000. From each palm of a pair of protective gloves two samples shall be taken (four samples in total). If the direction of manufacture of the

35、 material is recognizable then one sample shall be so taken that the longitudinal axis lies in the direction of the manufacture and one in the direction at right angles to it. If the direction of manufacture is not given and one cannot be established then the two samples are taken in two directions

36、at right angles to one another. The samples are taken without seams. If this is not possible then the sample is taken in such a way that the seams lie, during the test, in the area of the clip and do not influence the bending. 5.3 Water penetration The test shall be carried out according to the whol

37、e glove integrity test described in ISO 15383, with complete immersion of the glove up to the wrist line only. 5.4 Extreme cold flexibility The test shall be carried out in accordance with ISO 4675 with a test temperature of (-50 2) C. From each palm and back of a pair of gloves a sample will be tak

38、en (four samples in total). If the direction of manufacture of the material is recognizable then one sample shall be taken so that the longitudinal axis lies in the direction of manufacture and one in the direction at right angles to it. If the direction of manufacture is not given and one cannot be

39、 established then the two samples are taken in two directions at right angles to one another. EN 511:2006 (E) 7 5.5 Convective cold 5.5.1 Principle The thermal insulation of a handwear is determined by measuring the power required to maintain a constant temperature gradient between the surface of a

40、heated, full-scale hand model and the ambient atmosphere. Design and construction of the hand shall achieve the same constant temperature over the whole hand surface (maximum deviation as specified in A.4). The gloves shall be stored at test temperature for at least 24 h prior to testing. The heat i

41、nput to the hand shall be sufficient to maintain a mean hand temperature in each zone in the range 30 C to 35 C at an ambient temperature, which is at least 20 C lower. 5.5.2 Apparatus The test apparatus consists of: hand model; climatic room; measuring equipment. See Annex A. 5.5.3 Test sample The

42、test sample shall be of size 9 (see EN 420). 5.5.4 Procedure The hand model is dressed with the test glove and placed vertically, fingers down in the test zone of the climatic room. The ambient temperature (TA) is set sufficiently low to meet the requirements of Annex A. The air velocity is kept at

43、(4 0,5) m/s and relative humidity (50 5) %. Alternative conditions may be used provided correlation between the results obtained is demonstrated. When the temperature of the hand (THand) and power consumption (QHand) have reached a steady state, the measurements are taken of their average values for

44、 a period of 10 min. The resultant thermal insulation is calculated by: HandAHandTRQTTI= TRI is the resistance to dry heat loss from the hand, which includes the resistance provided by the handwear and the air layer around the dressed model; THandis the mean surface temperature of the measuring zone

45、 of the hand, in C; TAis the mean temperature of the air in the climatic room, in C; QHandis the measured power supply to the measuring zone of the hand during steady state, in W/m2. EN 511:2006 (E) 8 The average of two independent measurements is used as the mean value for the test glove. 5.6 Conta

46、ct cold The test shall be carried out in accordance with ISO 5085-1 using a pressure of 6,9 kPa and expressing the results in m K/W. Two representative samples of the material used to construct the palm side of the fingers of the glove shall be tested. If this is not possible, then sufficient sample

47、s shall be taken from the palm side of a number of gloves. If the palm side of the glove is not uniform, then samples of the different parts of the glove shall be tested and the lowest mean value quoted. NOTE an alternative test method may be used provided it has been cross-validated against the met

48、hod described above. EN 511:2006 (E) 9 6 Marking The marking shall comply with the appropriate clause of EN 420. In addition, the pictogram ISO 7000-2412 for the cold protective gloves shall be included with reference of the standard and the performance levels indicated as shown in the example hereu

49、nder: EN 511 2 3 1convective cold contact cold water penetration Figure 1 The pictogram shall be used only if a minimum level of 1 is obtained for convective cold according to 4.5 or contact cold according to 4.6. The sign X, instead of a number, means that the glove is not designed for the use covered by the corresponding test. 7 Information supplied by the manufacturer The information supplied by the manufacturer shall be according to the appropriat
